过去我厂使用的内热式中温电极盐炉C-100、C-25,它的坩埚原来是用耐热不锈钢铸造成的,一般使用4～5个月底部便被烧坏;如果采用较高的温度(980℃快速加热),最多只能用3个月。本厂自己铸造的坩埚使用寿命更短,用不了一月便烧坏了(砂眼处漏盐)。耐热坩埚使用期限不长便要消耗大量的耐热钢,而耐热钢的供应目前却相当困难。在这种情况下,我们想出了一个办法,用H-4耐火砖砌坩埚,结果使
In the past I used in the factory temperature thermal electrode salt furnace C-100, C-25, the crucible was originally made of heat-resistant stainless steel casting, the general use of 4-5 months at the bottom will be burned; if the higher Temperature (980 ℃ rapid heating), can only use up to 3 months. Our own casting crucible shorter life expectancy will not burn in January (trachoma Department salt). Heat-resistant crucible life is not long to consume a large number of heat-resistant steel, heat-resistant steel supply is quite difficult. In this case, we came up with a way to use H-4 refractory brick crucible, the result so that
